I think Brendan and I were seeking to clarify that whilst the original post is in the BRC Storage and Distribution section of the forum, the blending process makes it completely out of scope of the S&D Std and should be audited against the Food Standard.(Coincidentally and confusingly, Section 9 of the S&D Standard gives a few options where open food handling can come under the S&D Standard, but oil blending is not one of them)
If Hadir's business additionally sells on some of the oils without any blending, that part could probably be audited against the Traded Products section of the Food Standard, but it depends upon whether the site actually takes title to the goods.
If all the oil is blended, then the Traded Products section is not applicable.
